This turbine is really two turbines in one. One turbine inside the other. The outer turbine is compose of vanes parallel to the axis of rotation This outer turbine will rotate because the left side is always opened to the wind, because of the 45 degrees that the vanes have with respect to the diameter of the outer turbine and will interact with the wind. On the right side the vanes are overlapping and will have little interaction with the wind. The inner turbine composed of vertical vanes will rotate because on the left side the wind is entering the turbine and pushing the inner turbine as it turns away from the wind. On the right side the inner turbine is turning into the wind, but it is being shield by the overlapping effect of outer turbine's vanes. This interaction of the two turbines will increase the overall efficiency of this turbine.
